What?

Go is all about mechanical sympathy, and is absolutely a high performance language. I guess it all depends on your context, though. If you're used to writing assembly or C, things may look different.

(A "for" loop expresses much more mechanical sympathy than a list comprehension, as an example.)

But at least in the context of application services -- programs that run on servers and respond to requests, typically over HTTP -- Go is the language to beat. I've yet to see an example of a program where the Rust implementation is meaningfully more performant than the Go implementation, and I've got plenty of examples where the Go implementation is much better.
